Cable TV Scanning

Continuing my saga of not getting channels in the bedroom TV, yesterday I ran cable to my neighbors pedestal beside me. Same thing, will not pick up channel's 2 thru 7, the local channels. Then I ran cable to a pedestal behind me in a new part of the park. Same story. I took out a part of the bulkhead in the storage area and I can see a splitter that looks like its at least a 4 part. But to get to it, I need to take out another wall. That will take some work. If I knew that was the problem, I would do it. Don't know what else it could be. The cable system is putting out he channels & the TV will pick up them, but will not in the bedroom unless you run the cable directly to the TV. Other than the living room & bedroom, there is a hook up for a TV in the kitchen & in the storage area to add a TV if you want to. If I take the wall down to get to the 4 way splitter I will remove it and just install 2 way splitter in place of it to get just living room & bedroom.....
Gdetrailer thanks for all that info. I understand some of it. I'm basically the guy that plugs into he pedestal & the rig & its suppose to work....

Yep, 4way splitter, that is most likely the culprit :M

If no need for the other two connections ditching the 4way and replacing with a 2way should take care of the issue. Sadly, sounds like a lot of work to get at it.. Doesn't sound like the cable Co is supplying as much signal as they should be, have seen them put in 4ways in homes and work fine on all TVs.. But in a park setting they most likely have very few home runs back to the cable main trunk so there most likely is dozens and dozens of splitters in your park which is a buzz kill for getting enough signal..

IF you needed 3 or 4 ports I would recommend an amplified coupler. Amplified couplers as the name says, includes a low noise preamp on each port output.. Typically gives you a 7 DB or so GAIN on EACH PORT.

Although, even if you still only need two ports, this coupler will be a upgrade over the passive splitters and you might find not only the cable works better but event the OTA antenna also if you need or want to use that.





That one is a 4 port, 54mhz-1Ghz to outputs and has 5Mhz-42Mhz return back to the input (used for Cable companies cable box communications).

I don't know how good that one is, I have a different brand 8 port that I use in my sticks and bricks for OTA outdoor antenna system, it was the only way I could get TV after they switched OTA to all digital.

Found this one HERE

54Mhz is plenty low, that will work fine with Analog TV channels down to CH2.

Uses a 120V to 15V DC wall hugging plug but since it is 15V DC you can rewire to use your 12V battery system (just pay close attention to the polarity of the splitter plug side)..
